Should I just honestly get over it ?

So I had a miscarriage march 28th . My going to be sister in law found out she was pregnant 2 weeks later . Well she is completely healthy and the baby. But it just hurts when she talks about the baby at times and today she found out that she was having a girl . But it honestly hurt because I should farther along then her and finding out what I was suppose to have and experience what she is but I'm not and it hurts. My boyfriend just says it eventually be aRe turn but it should of been are turn now . Don't get me wrong I'm happy for her and every thing but just wish it was me . And I don't know if I should just get on with it and forget the act like nothing happen as if I never was pregnant and act even more happy or what ? I'm really confused
